50. As shown, I provide a cross rod 60, the

ends of which are connected to. wedgeshaped slide blocks6lmountedin guide ways 62, for

engagement with the rollers 41 of the operating rods 39. So far; this construction is identically the same as that shown in Figures suitable collar 65 connected" with the radiator l 16. This feed nut 64 is turned by means of a V V ofthejsidesof the'hood links pivotally con-j operating the pivoted shutters l to 6 inclusive. In this form of the invention I provide the cross rod withavertical ly disposed threaded feedjrod63, whichfre-- ceives a feed nut 64 anchored in place; by'a beveled gear 66, keyed or otherwisesecured to anoperating shaft 67, which extends'for-s wardly from the dash board68 ofthe vehicle.- The rear end of theoperating shaft is provided with an operating crank 69, so that the Operator of the vehiclecan readily turnthe, same. The beveled gear 66 'meshes with a beveled gear ,7 O formedon orsecnred to said feed nut. It is obvious that upon rotation of the shaft 67' that the'nut will be turned Y e 1 ment with the slide blocks, 7 secured to, the; inner face Consequently oving up or down the wedge block 61; I U v i V From theforegoing description, it cambe} I seen thatI haveprovidednovel means for? p h or louvers jof the sides of an automobile hood.
